Recent, widely recognized changes in the Earth system are, in effect, changes in the coupled human–environment system. We have entered the Anthropocene, when human activity—along with solar forcing, volcanic activity, precession, and the like—must be considered a component (a ‘driver’) of global environmental change (Crutzen and Stoermer 2000; Levin 1998). The dynamic non-linear system in which we live is not in equilibrium and does not act in a predictable manner (see Fairhead, chapter 16 this volume for further discussion of non-equilibrium ecology). If humankind is to continue to thrive, it is of utmost importance that we identify the ideas and practices that nurture the planet as well as our species. Our best laboratory for this is the past, where long-, medium-, and short-term variables can be identified and their roles evaluated. Perhaps the past is our only laboratory: experimentation requires time we no longer have. Thus the integration of our understanding of human history with that of the Earth system is a timely and urgent task. Archaeologists bring two particularly useful sets of skills to this enterprise: how to collaborate, and how to learn from the past. Archaeology enjoys a long tradition of collaboration with colleagues in both the biophysical sciences and in the humanities to investigate human activity in all planetary environments. Archaeologists work alongside one another in the field, live together in difficult conditions, welcome collaboration with colleagues in other disciplines—and listen to them carefully—and tell compelling stories to an interested public. All are rare skills and precious opportunities. Until recently few practitioners of biophysical, social science, and humanities disciplines had experience in cross-disciplinary collaboration. Many scholars who should be deeply engaged in collaboration to avert disaster (for example, specialists in tropical medicine with their counterparts in land use change) still speak different professional ‘languages’ and have very different traditions of producing information. C. P. Snow, in The Two Cultures (1993 [1959]), was among the first to warn that the very structure of academia was leading to this serious, if unintended, outcome.
